To all whom it may concern:

113e, it, knownth at I, Gnomes E. SoHN IpnR, apitiae'u oftho United States, residing in gle city and, county of San Franc sco and .j tate of California, have invented certain r consumed, and during the c peration of drying, to remove the volatile products from the charge, separate froin'said products the condensablc portions, and deliver the uncondonsable portions under pressure to the fire, for consumption, the whole device during operation being effectually closed to the escape of allvapors and odors.

To. this end my. invention consists in the novelgarbage incinerator whioh'I'shall now 2 fully describe" by reference to the accompanying drawings. in'which,

. Figure 1 is a yertical longitudinal section, broken and partly in lei-ation, of my garbags incinerator.

@The roof 7 of the fire. flue 3 is ,ar ched as seen 3,.and the b'iicl; work or. setting of this a'rch is continued to form an arched 'inclfosu rei ,or housing, 8 011 the revolving fdrumff'9. "Between'thearch of the housing V. .the larche'd roof, 10 10f. thelmain" setting 1s 'TIfor re airs.

out of undesirable and ofi'cnsivc matters and odors Access to those fines 12 is had throughtheencl plates 15, seen in Fig. 2, each plate covering the end communication p: a pair of lines.

The drum 9 is an elongated cylindrical structure, set atan inclinatiol'i from head to having on its' interior the lifting Said drum is 8 carried upon rollers 17, and having a rotary motion imparted to it by means of a gear 18 on each end. Poweris led in from the pulley These bevel, gears mesh with bevel gears 22 on shafts '23, which carry at their other ends nieshingwith bevel gears In'fthf head end tofthe drum 9 is a feed gate, 28,11gs. 1 Land 2, with sidewings 29, adap'tedwhen the gate is opened outward to ,jfo rm a closure with the feed hopper 30.

Thls hopper is supplied either by direct dumping throngh a top gate 31, or by'n eans Offfln 'el'ey'a'to'r '32, shown in Fig. 1. In the head end ot the di'um is also an air opening con rolled V asliding dz111'1per34, Fig. 'At the foot of. the drum is a discharge ,gate35 against and in contact with which the dnuin rotates.

This gate is hung from a hollow a n1 36, the upper end of which is axially p voted upon the driving shaft 37 of ,the fan 38, as seenin Fig. 4. The upper end of the hollow aiun36 communicates with the suction side of the fan 38', and the lower end communicates with the interior of the drum.

Said gate, therefore swings to and fijom its drum, being normally and adapted to be swung ,denser 40 containing a cooling coil 41. The

Ito'pof the condenser is fitted with a pipe 42 oontrolled .by a valve 43, said pipe entering the stack 14. ,This pipe also communicates a tank on top of hefinain setting 1. .A bafiler plate 46 is i'fi tted under-the end offth'e pipe 44 within the tank. From said tank 45 leads a pipe 47 down to a nozzle 48 extending into the fire chamber 2. The bottom of the con- 19,see Fig. 5, to a side shaft 20, F carrylng at each end a bevel gear 21.

fl ll l ll) denser 40 has an outlet pipe 49 from which leads a controllable discharge pipe 50, to any suitable destination.

In the wall of the main setting 1, above the fire chamber 2 is a chute 51 lying under the foot of the drum. This chute has a top hopper 52 and is controlled by an inclined gate 53 adapted by means of a handle 54 to be slid back and forth to cover and to uncover the chute 51. The gate 53 slips sufficiently freely through the wall of the hopper 52, to provide for the escape from the hopper, over the surface of the gate when closed, of liquid condensations, into the pan 55 from which a delivery pipe 56 leads.

Secured to the foot discharge gate 35 is a hood 57 which at its upper end opens into the drum while its lower end normally covers the pan 55 and the hopper 52.

In Figs. 1 and 4, 58 indicates a fuel burner as the source of heat.

The operation of the device is as follows:

Heat is supplied from the burner 58. The garbage is supplied to the hopper 30 and by the hopper is fed to the drum 9 through its feed gate 28. When the drum is charged, the supply of garbage is arrested and the feed gate 28 is closed. The drum being rotated, the garbage is-kept stirred up by the flanges 16 in the drum. As the garbage is heated, the volatile products are driven off and are sucked out through the hollow arm 36 by the fan 38 and by said fan are forced into the condenser 40. Such of these volatile products as, are condensable are trapped from the base of the condenser and led away through the delivery pipes 49 and 50. Such of the products as do not condense are forced by the fan from the condenser through the pipe 44 into the tank 45, from which they are driven through the pipe 47 and nozzle 48 into the fire chamber 2, wherein they are consumed. As these volatile products enter the tank, their velocity is sufficiently slowed up, assisted by the bafiie 46, to enable such condensable portions as may remain, to separate'out. As the operation proceeds and the drum contents become drier, the decreasing .volume of vapors may be allowed to pass directly into the stack 14 through the valve 43.

At the. beginning of and during the opera tion such liquid condensations as may settle from the drum contents trickle out from the foot of the drum, past the foot of the gravity through the chute 51 is delivered directly into the fire and is consumed.

The products of combustion from the furnace, by their long passage through the zigzag flues 12 are relieved of their objectionable matters which settle out and ma be cleaned from the flues through the end ates 15, thus leaving the products, which nally pass from the stack, relatively innocuous or unobjectionable. The drum by being wholly housed within'the arches or secondary setting 8 is protected from the direct fire and will therefore be durable.' During operation the several closures, namely the gates 28 and 35, the-hood 57 and the closed vapor passages, effectually confine and keep under control all odors and thus remove the objecv tionable feature of incinerating garbage.
